RAFAH, Gaza Strip (AP) — After more than three weeks of siege, the first Palestinians — dozens of dual passport holders and seriously injured — were allowed to leave Gaza, where Israeli airstrikes pounded a refugee camp for the second day Wednesday.

Even as bombings have driven tens of thousands from their homes and food, water and fuel run low, no one has been allowed to leave the embattled enclave, except for four hostages released by Hamas. Another captive was rescued by Israeli forces earlier this week. But a limited agreement appeared to have been reached Wednesday.

Meanwhile, Al-Jazeera television, one of the few media outlets still reporting from northern Gaza, aired footage of devastation in the Jabaliya refugee camp near Gaza City and of several wounded people, including children, being brought to a nearby hospital. The Hamas-run government said the strikes killed and wounded many people, but the exact toll was not yet known.The Al-Jazeera footage showed nearly identical scenes as the day before, with dozens of men digging through the gray rubble of demolished multistory buildings in search of survivors.

The toll from Tuesday’s strikes was also unknown, though the director of a nearby hospital said hundreds were killed or wounded. Israel said those strikes killed dozens of militants, including a senior Hamas commander who was involved in the militants’ bloody Oct. 7 rampage that ignited the war, and destroyed militant tunnels beneath the buildings.

The isolated Palestinian enclave, home to 2.3 million people, is in the grip of a severe humanitarian crisis amid a siege imposed by Israel in the wake of the Oct. 7 attack. Over half the population has fled their homes, and supplies of food, medicine, water and fuel are running low. A territory-wide blackout has left hospitals reliant on generators that could shut down soon as Israel has barred all fuel imports.
